APPARATUS FOR PRODUCING CURRENTS OFPURE 0R CARBURETED AlR.

SPECIFICATION forming part of Letters Patent No. 272,002, dated February 6, 1883.

Application filed July 20, 1882. (No model.) Patented in France in Germany June 21, 1882, No. 3,898; in Austria June 21. 1882 Italy July 12, 1882, No. 14,378 in RussiaJ'nly 12, 1882, and in To all whom it may concern:

Be it known that l, EMILE VIGREUX, a citizen of France, residing at Bois-Guillaume, in the Republic of France, have invented certain producing a continuous current of pure or carbureted air, substantially-for the transfer- I do hereby declare the following to be a full,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference which form a part of this specification.

My invention relates to improvements in apparatus for torcin g, compressing, and purifying air, and for impregnating or saturating scribed, and shown in the accompanying drawings, in which- Figurel is a longitudinal vertical section, andFi g. 2 a horizontal transverse section on and purifying air, and for impregnating or" saturating the same with liquids, constructed according to my invention. i t

O 0 indicate two shells or casings, having of any suitable material, such as sheet metal. Between the inner shell, 0,- aud the outer that wind spirally around theinner cone from o,owing to the conicalform of the supporting and inclosing shells G G, gradually decrease in diameter from their inlet-orifice c, at the said base of the cone, to their outlet orifice 0 the base of the cone the outer shell, 0, is extended some distance beyond the inner shell, 0, thus forming an annular space or chamber, B, within which is located the"air-inlet pipe vided with a like chamber, B, in which is located the outlet-pipe P. It will thus be seen that air is admitted to the passages through pipe P, discharging into chamber B, and the March 24, 1882, No. 14am; in Belgium June 21, 1882. No. 42,231; No. 20,972; in England June 21, 1882; in Spain June 26, 1882; in Sweden July 12, 1882.

atp, and the air-outlet pipe P passes through 7 like openings in the front of chamber .13 and the casing D, where it connects with a delivery-main, P The pipes P P are constructed to form bearin gs b b, respectively, for the trunnions or shaft upon which the coneG G, with itschambers B B, is mounted, and in which the said trunnions or shaft and the cone rotate. Motion may be imparted to the conein any desired'manner, either by prolonging the shaft at one end or one of the trunnions, so as to pass through either the inlet or outlet pipes and project beyond the casing D, 7

upon which projecting end a driving-pulley may be mounted, or, as shown in the drawings, by attaching to or forming on the chamber B a cogged rim, 11 to which motion may be impartedfrom a pinion, P driven from any suitable prime motor-such as steam or other motive power-through the medium of a belt-pulley, p or said cone may be rotated by a worm-gearing or "other suitable or preferred means. Each of the pipes P P at their upper ends isprovided with a branch pipe, p 10, one of which is shown in full in Fig. 2, said branch pipes having the form of 21. segment of the circle described by the inner peripheries of the respective chambers within which such pipes are located, and said branch pipes serve as hoods to prevent any liquid dripping from the annular wall of the chainbers to enter said pipes.

If the apparatus is to be employed for coolin g, purifying, and compressing or forcing air, the inclosing case is filled with cold water to a point on a line with the axis of the cone (3 C, or to a point slightly above said axis; and if the apparatus is to be used as a carburetor let pipes are stationary, and that the liquid inthe tank has free access to the chambers B B and the passages c.

The operation of the apparatus is as follows: One-halt, or less, of the inlet and outlet orifices c c of the passages are always above the liquid; but owing to'the spiral arrangement of these' passages those whose inlet-orifices are above the level of the liquid have their outlet-orifices immersed in and sealed by the liquid, and vice versa. The air coming in atp enters chamber B and fills the'larger end of those passages that have their inlet-orifices above the level of the liquid. 1f the cone is now rotated, the passages partially filled with air will be immersed, one after another, at their inlet end, and-while their outlet end is yet also immersed; The liquidwill'rush in, and owing to the greater capacity of that end of the passagesc a greater volume of liquid than that contained-in the discharge end ofsaid passages willfirst imprison the air and then compress and force it through the liquid at the smaller end before the outlet-orifices of the respective passages have emerged from the liquid. In this manner a constant flowof cool and purified or of earbureted air, as the case may be, is delivered by the apparatus for further use. said air being delivered in a uniform volume and at a uniform pressure to the pipe P. From the latter pipe it may be conveyed to a receiver, or to a net-work of distributing-pipes, or to a gasometer, according as the apparatus is used for purposes of cooling, purifying, and compressing air,-or as a carburetor.

The advantages of the construction of apparatus described may be briefly enumerated as follows First. The spiral passages being made to gradually decrease in capacity from the inletorifice to the discharge-orifice, the current of I the liquid is greatly accelerated and the air compressed and forced through the narrower end of the passages.

Second. The pressure being exerted solely upon the interior walls of the cone, it offers no resistance to the movements of said cone, and no provision need be made against the escape of the purified or carbureted air. Oonsequent ly either an open casing or a casing having a movable lid may be employed.

Third. The passages being arranged one by the side of the other, separated by partitions of equal thickness, and said passages being all of a like capacity, the inlet portion thereof in communication with the atmosphere will always take up a uniform volume of air, thereby producing at the discharge end of the appara tus acurrent of uniform volume and pressure.

Fourth. Owing to the spiral arrangement of the passages 0, their discharge ends are yet immersed in the liquid when the air is expelled therefrom by said liquid entering their inletorifices, thereby forcing the air through the body of such liquid, whereby said air may be thoroughly cooled and is thoroughly purified or carbureted.

Having now described my invention, what I claim is- 1. In an apparatus for cooling, purifying, and compressing air, or for carbureting air, a rotatable truncated cone having a series of spirally-arranged peripheral passages open at both ends, in combination with a tank or inclosing case adapted to contain a liquid,within which said coneis partially immersed,where-' by one portion of said passages may be sealed and the other portion placed in communica tion with the atmosphere, substantially as and for the purposes specified.

2. In an apparatus of the class described,

the combination of a rotatable truncated cone having a series of spirally-arranged peripheral passages, and a chamber at each end of said cone, a stationary inlet and a stationary outlet pipe, the former located within the chamber, at the base of the cone, and the latter withinthe chamber, at the truncated apex of the cone, in combination with atank or in! closing case adapted to contain aliquid, within which the cone is partially immersed, whereby air ted in at the base of the cone is made to fill a portion of the series ofspiral passages, and is compressed within said passages and forced through the liquid by the liquid itself when the cone is rotated, as described.

- 3. The combination of the cones G O, having a chamber, B,'formed at one end, provided with a cogged rim, b the induction a-ndeduction pipes P P, constructed to form hearings in which said cone rotates, an inclosing case or tank, and means, substantially such as described, for rotating the cone within the tank,- as and for the purposes set forth.

4 4. The combination, with the inclosing case or tank D, of the cones O O, havingispirallyarranged passages c, the chambers B B,- and the pipes P 1?, all arranged and constructed to operate substantially as and for the purposes specified.

In testimony that I claim the foregoing I have hereunto set my hand'this 12th day of June, 1882. 1 a
